At a glance

CVE-2026-12937 is a high-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the Tourfic WordPress plugin, affecting versions <= 2.22.7. It carries a CVSS score of 7.5 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires no authentication. The issue is fixed in version 2.22.8; sites on affected versions should update now. Disclosed June 2026, reported by Wordfence PRISM.

Vulnerability Overview

The Tourfic – AI Powered Travel Booking, Hotel Booking & Car Rental WordPress Plugin plugin for WordPress is vulnerable to generic SQL Injection via the 'post_id' parameter in all versions up to, and including, 2.22.7 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. The AJAX handler is registered for unauthenticated users via wp_ajax_nopriv_tf_room_availability, and the required nonce is emitted on the public single-hotel page template, allowing unauthenticated attackers to freely obtain a valid nonce and reach the vulnerable code path.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user. A successful exploit has high impact on confidentiality.

CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Tourfic <= 2.22.7 carries this weakness at post_id, and reaching it takes no account at all. SQL injection happens when request data is concatenated into a query instead of being bound as a parameter, letting an attacker change the structure of the statement rather than just its values.

A working injection can read any table the database user can see, which on a WordPress install means user records, password hashes and session or API secrets stored in options. For Tourfic the fix is 2.22.8: builds <= 2.22.7 are affected, anything from 2.22.8 onward is not.

Remediation

Update to version 2.22.8, or a newer patched version

How does WordSec protect against this?

Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Tourfic 2.22.8 closes this, and updating the plugin is the step that ends it.
